i l 'ro ALL WHoM IT MAY eoNcEnn:

Be it known that I, AR THUR PBEN'I'ISS, of Prentiss Vale, McKean county,State of Pennsylvania, have' invented new and nsefulimprovements inInstruments for'Medieal Inhalation; andI do lerebydeclare the followingto be a Ifull and exact description of the same, reference being had tothe drawingswhich accompany and form a part of these specifications,in'which l Figure I shows the article entire in one form .of structure.

Figure II, vien' of theinstrument of another form of structure,sectional. Figure III, a sectional view of cap-and Stoppers at the largeend. Figure 1V, sectional view out in a line at P,\ showing -guard corkplaced in neck. v Figure V, view of small cup and month-piece,'xvitl1cork to stop small end of the tube A.

Letter A, a small glassxtube, and may be of the same diameter at bothends, or one end may be larger, a's "shown at 2. -Letter B, sponge or'other porous substance that will readily absorb liquids, the medicinebeing prepared in the liquid forni: LetterC, circle of rubber lying atbottom of the clip E. Y

A For the1 convenience of the pocket, or to carry in yreticulevortrunk,the stoppers E E, caps g g', and cords or chains .i t' are :used to.close each end of the tu'oe A. Theform shown in Fig. II may sometimesbe more desirable," asalfoidingopportunity to apply the medicine to thesponge while theinstrument is in use; o r, the glass may be larger inthe ccntr e,' as shown by the figure red lines, thefsponge being forcedin while dry, and 'the medicine pour'edin afterwards' at 'one 'endlPersons needing inhalation'for those suiering from cutarrh,

iuanimation of the fauces or tensile, bronchial irritation or pulmonarytendency,- are very often able to, and are, travelling about.; hence apocket inhaleror one safely carried in valise or trunk, and possessingthe propertyof lbeing cleansed readily, would 'be of great yalue. N

In constructing these implements I make the tube and stoppers plain,removing' the Stoppers when vused ;l or, I -form a. grooveor grooves inthe stoppers, as seen in Figs. 'III and IV, lso that, when said Stoppersare partly drawn, the air may flow in around the large stopper, andvbedrawn out at the smaller end; or, a hole may be made in the end at 0';`'and then it would only be necessary to turn the stopper partly around,or till one of the grooves in the cork comes'in 'conjunct ion with thesaid openingO, and the air may enter this way; or, grooves partly in theStoppers and partly-in the walls of the tube may be adopted as eans ofclosing and opening theA ends. 'lzlxe stoppers would be removed when itwas desirable to inflate the lungs quickly, but leftl in when whenitma's desired to -inlate them slo'wlylan'd byeortion. When the bo'dyofthe implement is fashioned as in lgllljhe end for the mouth 'may bebent, as shown, or it may be left straight, and a bent monthpieceinserted, as shon'n by the red lines in Fig..-II. -When the 'small cap gis turned close the cork in'it is pressed-'down on to another fixedfirmly in the neck of the tube atm. For durability and hard usagel thewhole implement may be formed or made oi` metal, hard-rubber, or'othersuitablematerial.v

. 'My invention "relates to improvements in themanuiacture of inhalersas to arrangement of parts, compactness, and portability, the latterproperty being such that the implement may be carried for days in thetravelling-trunk, or in the pocket about the person, without removingthe medicine, -asit is corked as tight as though in a separate vial.'

"What Iclui'm as myinvention, and desire tmsecure Letters Patent, is

' An inhaler, when formed and its various partssrrunged substantially asdescribed und for the purposes set forth. l v .ARTHUR PRENTISS.
